Changes

This is just a selected list of some of the more notable changes. The numbers refer to the Perl repository change numbers; see Changes58 (or Changes in Perl 5.8.1). In addition to these changes, lots of work took place in integrating threads, PerlIO, and Unicode; general code cleanup; and last but not least porting to non-Unix lands such as Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic, and EBCDIC.
